WorkflowService/GQuery seem to have issues when fields are aliased in the query

[kinow]

Describe the bug

A query such as:

subscription {
  cyclePoints: familyProxies(ids: ["root"]) {
    cyclePoint
  }
  familyProxies (exids: ["root"], sort: { keys: ["firstParent"]}) {
    id
  }
}

Ends up with two FamilyProxy selections in the GraphQL Query JS object. One of them contains an "alias" cyclePoints as specified in the query.

But the Vuex store ends up with an object missing cyclePoints. Probably just needs to use the alias when it is present, or the name otherwise.

Release version(s) and/or repository branch(es) affected?

Steps to reproduce the bug

Use a GraphQL query with an alias.

Expected behavior

A JS object is added to the store with both familyProxies and cyclePoints.

[kinow]

The alias comes from an improvement reported in #354 to avoid going through family proxies to find the cycle points.
